BOOT FAILURE ISSUE Windows Home Server

I had a functioning Windows Home Server (WHS) and it suddenly restarted and now fails to boot with a BOOT FAILURE message. The system has 2 eSata drives and the OS is on A 20 GB drive D: partition that WHS sets up on the secondary drive.

I have:
1. Run the SpinRight diagnostics on all drives and all seems fine.
2. Used the Recovery Console from Server 2003 to look at the system and it sees the D:\WINDOWS system and allows me access with my Admin password.
3. Ran CHKDSK /P and all reports fine.
4. Ran FIXMBR and FIXBOOT and although both reported success, I still get the same BOOT FAILURE error.

Any suggestions on what to do next will be appreciated.

Thanks
Fred
